ATX 3.0 1500W platinum power supply
The be quiet! Straight Power 12 BN518 is a fully modular ATX 3.0 power supply rated at 1500 W. It carries 80 PLUS Platinum certification with up to 93.9 % efficiency. A single 12 V rail delivers the full output for high-end desktop systems. Japanese 105 °C capacitors and full bridge LLC topology provide stable power delivery.
PCIe 5.0 and 6+2 pin connector limits
The unit includes four PCIe 6+2 pin connectors for graphics cards. ATX 3.0 compliance allows the PSU to handle massive power excursions up to double its rated power for short periods. The 135 mm Silent Wings fan with funnel-shaped opening maintains high airflow at very low noise levels. Active PFC and full protection circuits guard against over voltage and overload conditions.
Single 12V rail with 1500 W continuous power
One massive 12 V rail supplies the entire 1500 W without multi-rail restrictions. This makes the PSU suitable for configurations that draw extreme transient loads from a single GPU. The 160 mm depth fits standard ATX cases. Nine SATA power connectors and a 20+4 pin main connector complete the cable set.

Questions sur cet article
Should I choose this 1500W Platinum model or a lower-wattage unit?
Pick the 1500W unit only if your build can draw near that level; the single 12V rail delivers the full 1500W continuously and the Platinum rating keeps efficiency up to 93.9% at typical loads.
What does the 1500W rating mean once the PSU is installed in my PC?
It means the unit can supply 1500W continuously on one massive 12V rail, with Japanese 105°C capacitors and full bridge LLC topology keeping voltage stable during heavy GPU and CPU loads.
How does the ATX 3.0 interface affect what I can connect?
The ATX 3.0 design includes native 12VHPWR support for PCIe 5.0 graphics cards while still providing four 6+2 pin PCIe connectors and nine SATA connectors for drives and peripherals.
